Deval Patrick declared a state of emergency Friday and banned travel on roads as of 4 p.m. as a blizzard that could bring nearly 3 feet of snow to the region began to intensify. As the storm gains strength, it will bring "extremely dangerous conditions" with bands of snow dropping up to 2 to 3 inches per hour at the height of the blizzard, Patrick said.
